I'm kinda worried about the drop off solo movies will have in light of Avengers. It's inevitable but still, even IM3 may have an issue. The Avengers movie, or the SHIELD movie almost need to be setups in of itself, just for the sake of hinting at or deliberately leaving material for Cap sequels. Maybe we will need a Red Skull "Mwwwwhahahaha" after credit scene or something. Avengers shouldn't be a climax by any stretch. Whatever the main threat is in the movie needs to be neutralized, but I feel we also need some setups for future Cap villains if they intend to make sequels. I actually have a feeling the SHIELD movie SLJ was talking about may end up featuring Cap regardless just to give the movie a true presence.
